MICHAEL HAUGHEY, on sr. LOUIS-,lVl'l-SSOURI M PR'oV-EMENI .I N RF'RIGERA'TO R CAR'S I Specification forming part of Letters Patent No.204,729, dated June 11, 1878 application filed April 10, 1878.

To all whom it may concern:

Be it known that I, MICHAEL HAUGHEY, of the city and county of St.Louis, and State of Missouri, have invented a new and ImprovedVentilating and Refrigerating Railroad-Oar, of which the following is aspecification:

Figure 1 is a longitudinal section of a refrigeratingcar constructedaccording to my improvement. Fig. 2 is a vertical transverse sectiontaken on line .00 w in Fig. 1. Fig. 3 is a detail view of thecar-ventilator.

Similar letters of reference indicate corresponding parts.

The object of my invention is to ventilate and cool railway-cars used inthe transportation of perishable articles.

In the drawing, A is a car having treble walls a b c, inclosing twospaces, d e. The inner space, d, is filled with granulated cork, or corkshavings, and the water-space 6 contains air. The outer wall of the-caris composed of siding ton gued and grooved together, to render it tightand weather-proof.

At the top of the car there is a ventilator, D, which communicates withthe air-space c, and causes a continual circulation through the saidspace, the air entering apertures in the side of the outer wall, nearthe bottom of the car.

The ventilator consists of a square box, open on opposite sides, andprovided with two doors, f, which are hinged to the sides of the box ator near its base, and are connected by rods, which are pivoted to bothof them, keeping the doors apart, so that only one at a time can comeinto contact with the side of the box. The wind closes the door on thewindward side of the ventilator, and by this means opens the door on theopposite side.

A chamber, E, is formed in the top of the car, near one end, and to itis fitted a box, F, which is provided with external flanges a on itssides, ends, and bottom, which touch the walls of the chamber and form acontinuous passage around the box from the air-inlet pipe g to theair-discharge pipe h.

A tray, t, of perforated metal or wire-cloth, is fitted to the top ofthe ice box F, for containing salt, and a wooden cover, G, is fittedover all. At one side of the ice-box F there is a cowl, H, which turnson the short vertical pipe, j, and is supported on a pivot, k, in thecenter of the said pipe. The pipe j communicates with the passage aroundthe ice-box.

A tube, 1, communicates with the interiorof the car, and its upper endprojects into a pipe, I, that extends through the side of the cowlopposite its mouth. To the outer end of this pipe a vane, m, isattached, for keeping the mouth of the cowl to the wind. The mouth ofthe cowl is provided with a wiregauze cover, to prevent the entrance ofcinders, and the lower end of the tube lis also covered with wire-gauze,to prevent the entrance of dust and cinders.

The cowl is provided with a damper or valve, n, which may be turned tocontrol the admission of air, and the pipe 1 is provided with a valvefor controlling the escape of air from the car.

The ice-box is provided with a drip-pipe, 0, which extends below thefloor of the car and discharges into a drip-cup or trap, p, whichpermits the water to escape, but prevents the entrance of air.

A pipe, q, connects the air-discharge pipe h with a box, T, whichreceives the moisture, dust, and cinder which pass the cowl.

An inverted siphon, s, connects the box 1" with the drip -pipe 0, andforms at the same time a trap, which prevents the air forced through thepipe g from escaping to the drippipe.

A tapering perforated pipe, I, projects from the box r, and distributesthe cooled and filtered air throughout the interior of the car.

The warm and vitiated air escapes from the car through the pipe I, whileany moisture that may drip from articles contained by the carescapesthrough a spring-supported door, t, at the bottom of a well or trap, u,in the corner of the car.

The car is provided with a number of transverse rods, c, from which tosuspend articles to be transported. A number of wire-gauze cases, to,containing charcoal is suspended from the rods 1;, to absorb gases givenoif from articles contained by the car.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. The combination, with chamber E, having 3. Theventilator D, having the connected pipe g, and car having pipe j, of thevalved hinged doors f, in combination with the re* cowl and pipe H I,supported on the pivot 70, said cowl having a wire-gauze at one end anda vane at the other, as and for the purpose set forth.

2. The combination, with car and icebox, of the drip-pipe o, pipe q, box1-, siphon s, and. perforated pipe I, as and for the purpose specified.

frigerator-car A, having the air-space a, substantially as shown anddescribed.
